N2  - This paper presents a summary of the development activities undertaken as part of the refinement and implementation of a new, federated analysis of sinking ships first presented at INEC 2020. The described approach uses a functional survivability analysis as the basis to generate a time domain sinking ship assessment and subsequent escape and evacuation analysis. The result of this approach is a time to sink based on a realistic input threat against which an escape time is generated using the same damage inputs and taking account of the environment and damage induced restrictions in the flow of evacuees. The approach is designed to replace fixed and empirically derived escape criteria with realistic scenario-based assessments which cover the range of likely threats leading to abandonment.
The methodology used leverages state of the art escape and seakeeping software using a survivability software model at its core. Results are driven by a large number of inputs for each software stage, all of which determine the complexity of the input modelling required and the processing time of the analysis. A sensitivity study has been conducted on an in-service Royal Navy platform and the results are summarised. The impact on assessment implementation is then discussed.
The practicalities of using the methodology to conduct whole ship assessments of naval platforms is further discussed. Through the conduct of this most recent study, a number of advancements and opportunities have also been identified and are presented.
